" JOHN It. RAY AND WILLIAM E. SANKEY, OF SALEM, MISSOURI.

TIME STOCK-FEEDER.

SPECIFICATION fOrIiling part of Letters Patent N 0. 760,482, dated May 24:, 1904. Application filed December 21, 1903. Serial 110.136.137. (N0 model.)

To all, whom it may concern:

Be it known that we, JOHN R. RAY and WVILLIAM E. SANKEY, residents of the city of of Salem, county of Dent, and State of Missouri, have invented a new and useful machine for feeding horses and other stock at a certain determinate hour by clockwork, to be called an automatic time stoclcfeeclerg and we do hereby declare that the following is a full, clear, and cxactdescription of the construction and operation of the same, reference being had to the annexed drawings, making a partof this specilication.

This invention relates to new and useful im' provements in automatic time stock-feeding apparatus, and comprises means whereby a hinged door may be automatically released by means of an alarm attachment to a clock at a predetermined moment, whereby food for animals may be automatically fed into a feedingtrough or manger, and in the provision of spring-actuated means for returning the door to its normal position.

The invention consists, further, in various details of construction and eombinatons and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claim.

e illustrate our invention in the accompan ying drawings, which, with the letters of reference "marked thereon, form a part oi this application, and in which drawings, Figure 1 is an elevation of our improved apparatus. Fig. 2 is a side view.

Reference now being bad to the details of the drawings by letter, A designates a chute through which food is adapted to be passed, and B designates a door which is hinged at C to the inner wall of the chute.

a designates an arm which projects through the wall of the chute and has a spring 0 secured thereto, which is fastened to a pin O, adapted to be held in a hole in the wall of the chute.

Supported upon a bracket-arm upon the side of the chute is a clock H, having an alarm at: tachment, and K designates a key which winds the spring mechanism of the alarm apparatus.

Projecting from said key is a rod N, which is adapted to rotate with the key as the same is turned in one direction or the other, and Q designates a stop which is positioned in the path of said rod N and against which the latter strikes to limit its throw in oncdirection or the other.

D designates a spring-pressed belt which is mounted in the wall of the chute, and projecting from said bolt is a finger D, to which a spring E is fastened, which in turn is secured to the wall of the chute. as shown. A cord F is fastened to an eye at the end of said bolt, and its other end is secured to the shank portion of the winding-key K and is designed to wind about the key for the purpose of withdrawing said bolt, the forward end of which is positioned underneath and adapted to sup port the hinged door when the same is weighted down by means of the food resting upon the same.

In operation our alarm apparatus is set so that the food may be fed to the stock at any hour, and as the spring of the alarm apparatus begins to unwind the key K, turning in the winding-post, will cause the cord F to wind upon the post K and withdraw the bolt D from underneath the free swinging edge of the door, allowing the food to fall down through the chute. After the food has fallen and the door is relieved of its weight the spring O will cause the door to resume its normal horizontal position. The bar N, coming in contact with the stop Q, will cause the post to stop its rotary movement, thereby allowing the bolt to be withdrawn only a sufiicient distance to allow the free swinging edge of the door to pass. As the door D returns to its normal position the bolt will be retracted, to allow the same to pass, after which it will resume its normal position and support the swinging edge of the door.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent. is-

An automatic time stock-feeder comprising a feeding-chute, a door hinged therein, an arm projecting from said door through the wall of said chute, a spring fastened to said arm and a pin to which said spring is secured, a springpressed bolt adapted to support the free swinging edge of said door, an alarm apparatus with winding-post, cords fastened to said bolt and adapted to wind about said post, an arm projecting from said post and a stop against which said arm is adapted to contact to limit the outer movement of said bolt, as set forth.
